Hi doctor,

I am a 41 year old female with regular periods. I am 5'4" and weighs approximately 165 pounds. I have fainted this morning and almost exactly a month ago. The first time was in the middle of the night. When I woke up to use the bathroom, and while I was in the toilet, I broke out in a clammy sweat. I made it to the kitchen and started getting real lightheaded and almost dizzy. I remember a little bit of spotty vision and ear ringing. I know I heard and felt hit the floor, but I do not remember going down. It seemed almost instant that I woke up still sweaty. Besides being in pain from the fall, I felt better. This morning, I woke up and started my routine just fine. After about 15 minutes of being awake and moving around, the same thing happened. I began sweating and getting dizzy. Fearing what happened last time, I consciously slide myself down to sit on the floor, but I still fell forward hitting my head on the table in front of me. Again, I was sweaty but felt better. Approximately, three years ago, my PCP diagnosed MS with my MRI, but my neurologist denied that.



Welcome to

  • It looks like a cardiac issue. It is most probably occurring due to fall in blood pressure and which is mostly due to either a vagal reflex or low heart rate. These can be vasovagal syncope.
  • During urination, one can get syncope because especially if one is straining during urination, it increases vagal tone and decreases heart rate leading to syncope.
  • Were you fasting for a long time, dehydrated, under stress or just came back from urination during the second time?
  • We need to evaluate you. You should get an ECG done, and you may need a Holter monitoring after ECG. Get your blood pressure and pulse rate checked. You will also need echocardiography and get sugar test as well.
  • In treatment, at this moment you should avoid risky activities like drinking and walk alone on the road. Do not strain during urination.
  • Drink plenty of liquids like water, ORS (oral rehydration salt solution), fruit juices, etc. Avoid dehydration and prolonged fasting. Also, avoid smoking and alcohol if any.
